It would we could select pos1 and pos2 and set it to a specific block, then we can create a spleef arena type thing using commandblocks. This will allow players to activate a switch and restart a spleef game automatically with WE and without a spleef plugin. There are many other more obvious applications such as RPG scripting and whatnot.

I use a plugin called CBWrapper to accomplish this.
Example of commands in 3 command blocks to reset your TNT spleef arena:
cb /pos1 0,64,0
cb /pos2 40,64,40
cb /set tnt

(note you must only place one / before the worldedit command as CBWrapper automatically adds a /)
